Description

cPanel contains a flaw that allows HTTP response splitting. This flaw exists because the application does not validate the 'failurl' parameter upon submission to the 'login/index.php' script. This could allow a context-dependent attacker to insert arbitrary HTTP headers, which are included in a response sent to the user.
